For me the only two unqualified world class players we have are Kane and Hugo. I would both in the top five of their positions, and would not be out of place on any team in the world (discounting styles of play, I just imagined Hugo playing the ball as much as he would at Barca.)
I absolutely love Eriksen but he suffers for the fact that his position is loaded with talent at the moment. I think he is probably the best AM in the league tbh but there is certainly a discussion between him, KDB, Hazard (who plays a very different game but same position), and others.
Dele certainly has the potential but I wouldn't take him over a great many AMs at the moment.
Toby might be, i just don't think I can judge defenders that well because they are less noticeable, especially when they are really fucking good, which is compounded by not watching much football outside the PL.
I would probably say that Moose is actually the closest to being world class behind Kane and Hugo, taking into account how almost every player that talks about him, on Spurs and other teams, say he is the best player they have played with/against. His skill set is so unique that it took years for him to find his best position at Fulham and here, so that slowed down his development and kept him under the radar. But if he was playing in the first XI of a big club like RM, Barca, or Bayern (which I think he absolutely could) he would be considered one of the best CMs in the world today.
